EEG-Based Decoding of Sound Location: Comparing Free-Field to Headphone-Based Non-Individual HRTFs

Nils Marggraf-Turley, Martha Shiell, Niels Pontoppidan, Drew Cappotto, Lorenzo Picinali · 2025

Sound source localization relies on spatial cues such as interaural time differences (ITD), interaural level differences (ILD), and monaural spectral cues. Individually measured Head-Related Transfer …

Binaural speech intelligibility in noise for hearing-impaired listeners.

 · 1970

The effect of head-induced interaural time delay (ITD) and interaural level differences (ILD) on binaural speech intelligibility in noise was studied for listeners with symmetrical and asymmetrical se…
